Bently Nevada 330104‑00‑07‑90‑02‑00 Detailed Product Overview
Brand Information
The Bently Nevada brand is a well‑established provider of industrial condition monitoring and machinery protection solutions. Its products are widely used in mission‑critical applications across power generation, petrochemical, oil & gas, pharmaceutical, and heavy industrial facilities. The brand is recognized for durability, precision, and reliability in vibration and displacement measurement instruments.
Product Series
The model 330104‑00‑07‑90‑02‑00 is part of the 3300 XL 8 mm Proximity Transducer System Series. This series uses eddy current sensing technology to measure shaft vibration and position without physical contact. The 3300 XL system is modular and scalable, supporting a range of probe configurations for diverse industrial requirements.
Product Description
The 330104‑00‑07‑90‑02‑00 is an 8 mm proximity probe engineered for non‑contact measurement of shaft vibration and radial displacement. The numerical suffix “90” indicates a specific system cable length or probe configuration tailored for longer measurement distances between the probe tip and the monitoring electronics. The “02‑00” portion of the model identifies specific cable and connector configurations optimized for industrial applications.
This probe generates a magnetic field at the sensing tip; as the rotating shaft or conductive surface moves relative to this tip, variations in that field are converted into a proportional electrical signal. This output is used by monitoring hardware in the 3300 XL series to assess machine health, detect imbalance, misalignment, looseness, or bearing deterioration.
The 330104‑00‑07‑90‑02‑00 is designed to perform reliably under harsh industrial conditions including high temperatures, oil contamination, dust, and mechanical vibration. It is typically installed in conjunction with extension cables and signal conditioning modules to form a complete proximity monitoring system.

Applications
The 330104‑00‑07‑90‑02‑00 proximity probe is used for continuous condition monitoring of rotating machinery where longer distance between the machine and the monitoring system is required. Typical application areas include:
- Steam turbines and gas turbines
- Large centrifugal and reciprocating compressors
- Industrial pumps in chemical and petrochemical plants
- Electric motors and generators
- Gearboxes and mechanical drive systems
- Fans, blowers, and other rotating equipment
The extended cable length makes this model suitable for facilities where the monitoring rack is located at a significant distance from the machine sensors.
